flutter 多语言国际化 flutter Intl的使用方法

news2024/11/30 18:14:46

一使用 flutter Intl

Android studio需要添加插件 flutter Intl

路径 File>>Settings>>Plugins>>Marketplace>>flutter Intl>>Install
安装插件重新启动Android studio

Android studio 创建一个flutter测试的新项目

在项目文件中配置 ** 添加完成需要flutter pub get
pubspec.yaml

  #国际化配置 1
  flutter_localizations:
    sdk: flutter
  #
  intl: ^0.19.0
  #生成文件
  intl_utils: ^2.0.0

使用插件生成配置文件

1.Tools>>Flutter lIntl>>Initialize for the Project

2.Tools>>Flutter lIntl>>Add Locale

看到{lib>>|10n}生成相关文件，文件内容{}
填写文件
中文

{
  "appName": "zq国际化{name}",
  "autoBySystem": "跟随系统",
  "theme": "色彩主题",
  "settingLanguage": "多语言",
  "darkMode": "黑夜模式",
  "language": "语言",
  "settingFont": "字体"
}

中文

{
  "appName": "zqinternational{name}",
  "autoBySystem": "Auto",
  "theme": "Theme",
  "settingLanguage": "Language",
  "darkMode": "Dark Mode",
  "language": "Language",
  "settingFont": "System Font"
}

重点 “appName”: “zq国际化{name}”,
{name}是一个占位符可以加入动态的字符，配置时都需要配置

执行 flutter pub run intl_utils:generate 生成相关文件

在项目文件目录 lib>>generated>>|10n.dart 看到如下文件

....
....
/// `zqinternational{name}`
  String appName(Object name) {
    return Intl.message(
      'zqinternational$name',
      name: 'appName',
      desc: '',
      args: [name],
    );
  }

  /// `Auto`
  String get autoBySystem {
    return Intl.message(
      'Auto',
      name: 'autoBySystem',
      desc: '',
      args: [],
    );
  }
